Answer:
4320 m
Explanation:
The relationship between speed, distance and time taken for uniform motion is
[tex]v=\frac{d}{t}[/tex]
where d is the distance covered, t the time taken, v the average speed.
In this problem, we know:
v = 18 m/s is the average speed
[tex]t=4.0 min \cdot 60 = 240 s[/tex]
Therefore, solving the equation for d, we find the distance:
[tex]d=vt=(18 m/s)(240 s)=4320 m[/tex]
